With the new release of the GCC 9 compiler the operation of -Wmissing-attributes warnings has also been extended to aliases: this causes a warnings if the alias has less attributes than its target.
This warnings does not actually indicate a problem in the mimalloc code and you could safely ignore it by adding "-Wno-missing-attributes" to the CFLAGS, however I was not going to use a "hack" to hide the warning when compiling alloc-override .c
So this patch solves the problem simply by using an attribute (present only in GCC> = 9) that copies the attributes of another function, since this attribute is exclusive only for GCC 9 (or later) I had to use a simple precompiler instruction to add the "copy" attribute only with GCC 9.
Some documents explain passing MIMALLOC_STATS=1 to print
statistics, though it handles as mimalloc_show_stats in the actual
code. According to the code, change the name MIMALLOC_STATS to MIMALLOC_SHOW_STATS.
Red Hat Linux was discontinued by Red Hat in 2003. It would make sense
to address glibc-based Linux distributions rather than Red Hat Linux.

Indention programs such as clang-format usually rely on the occurrence
of statement terminator, otherwise they are likely confused. The revised
forwarding macros do not contain semicolons character, which is friendly
to indentation or style checkers.
